A little over a year ago, Caltech's Lihong Wang developed the world's fastest camera, a device capable of taking 10 trillion pictures per second. It is so fast that it can even capture light traveling in slow motion.

An organism's genome contains all of the information necessary for each of its cells and tissues to develop and function properly. Written in DNA, each individual gene encodes for something, whether it is a structural protein that helps define a tissue's shape, an enzyme that catalyzes the chemical reactions of life, or a signaling protein that cells use to communicate.

As the planets in our solar system go around the sun, they tug on it, causing it to wobble. Jupiter, our most massive planet, yanks on our sun to a significant degree, whereas Earth, which is tiny by comparison, exerts a much weaker tug.

On April 25, 2019, the LIGO Livingston Observatory picked up what appeared to be gravitational ripples from a collision of two neutron stars. LIGO Livingston is part of a gravitational-wave network that includes LIGO (the Laser Interferometer Gravitational-wave Observatory), funded by the National Science Foundation (NSF) and the European Virgo detector.

Atomic clocks are used around the world to precisely tell time. Each "tick" of the clock depends on atomic vibrations and their effects on surrounding electromagnetic fields. Standard atomic clocks in use today, based on the atom cesium, tell time by "counting" radio frequencies.

The decision to buy a lottery ticket, gamble on a stock, or buy an insurance policy often comes down to an assessment of risk. How much do I have to lose or gain? For centuries, economists have debated about when somebody should take or walk away from a bet.

A rare asteroid orbiting snugly within the inner confines of our solar system has been discovered by Caltech's Zwicky Transient Facility, or ZTF, a survey camera based at Palomar Observatory. The newfound body, named 2020 AV2, is the first asteroid found to orbit entirely within the orbit of Venus.

Researchers at Caltech have demonstrated that machine-learning algorithms can monitor online social media conversations as they evolve, which could one day lead to an effective and automated way to spot online trolling.

A new panoramic image based on data captured by NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) shows the bustling center of our galaxy like it has never been seen before. SOFIA is an airborne observatory that flies up into the lower regions of the stratosphere, about 40,000 feet above Earth, to capture infrared images of the cosmos.

The brain's complex tangle of interconnected nerve cells processes visual images, recalls memories, controls motor function, and coordinates countless other functions. A major goal of neuroscience is understanding how the brain is "wired"-in other words, how do all of its neurons know how they should connect to each other to achieve optimum function?
